The present invention is directed to novel tricyclic antidepressant drug derivatives synthesized for covalent attachment to proteins or polypeptide antigens for use in the preparation of antibodies or receptors to tricyclic antidepressant drugs and tricyclic antidepressant metabolites. The new derivatives are characterized by a saturated double bond on the amitriptyline portion of the molecule and are represented by the structure
where R1 is a saturated or unsaturated, substituted or unsubstituted, straight or branched chain of 0-10 carbon or heteroatoms, X is a linker group consisting of 0-2 substituted or unsubstituted aromatic rings, and Y is an activated ester or NH—Z, where Z is a poly(amino acid). The novel tricyclic antidepressant activated hapten derivatives are useful for preparing tracers and conjugates for tricyclic antidepressant immunoassays, including an enzyme immunoassay and a microparticle capture inhibition assay using an antibody produced from the novel immunogen with a conjugate derivatized either at the N-1 position of imipramine or at the C-2 position of dihydroamitriptyline.
本发明涉及一种新型三环抗抑郁药物衍生物,该衍生物经合成可共价连接到蛋白质或多肽抗原上,用于制备抗体或受体以对抗三环抗抑郁药物和三环抗抑郁药物代谢物。新的衍生物的特点是分子中的阿米替林部分具有饱和双键,其结构表示为R1是0-10碳或杂原子的饱和或不饱和、取代或未取代的直链或支链,X是由0-2个取代或未取代的芳香环组成的连接基团,Y是活性酯或NH-Z,其中Z是多肽(氨基酸)。这种新型三环抗抑郁药物活化半抗原衍生物可用于制备三环抗抑郁药物免疫分析的示踪剂和结合物,包括使用从新型免疫原产生的抗体制备的酶免疫分析和微粒捕获抑制分析,其中结合物在氨替林的N-1位置或二氢阿米替林的C-2位置衍生化。
